. 1 .This invention relates to a folding metal awning. It has for itsmain objects. to provide such an. awning, that will be highly efficient.for. the purpose intended, simple in structure, cheap to manufacture,easy to use, and extremely durable.

Such structures have been devised in an attempt to provide a metallic:type of awning. However, they have not proven entirely satisfactory as aresult of being relatively complicated, cumbersome and expensive tomanufacture.

Other objects and advantages will appear from the drawings anddescription.

By referring generally to the drawings, part of this application, itwill be observed that Fig. 1 is a front elevational View of an awningmade according to the present invention in open condition for use overthe upper portion of a window; Fig. 2 is an end view of Fig. 1; Fig. 3is a detail view on line 33 of Fig. 4 showing how the awning slats areattached to the supporting expandable arms; Fig. 4 is an enlargedfragmentary view showing the upper end portion of the awning and windowframe; Fig. 5 is an end view showing the awning in near complete foldedcondition; Fig. 6 is a plan view of one of the slats of the awning; Fig.7 is an end view of Fig. 6 on line 7-1; Fig. 8 is a sectional view online 88 of Fig. 5 showing one end of the assembly; Fig. 9 is an end viewof Fig. 8; Fig. 10 is a view of Fig. 11 on line I0lil; and Fig. 11 is aside view of one end supporting means in expanded condition.

Similar reference numerals refer to similar parts throughout the severalviews.

Referring to the drawings in detail it will be seen that the assembledawning comprises slats I, 2, 3, 4 and 5 attached by their ends tobrackets 6, l, 8, 9, l0 and II that are pivoted at I2, l3, l4, I5, l6and I! on expandable arms l3, I9, 20, 21, 22, 23, 24, and 25. lhe edgesof the slats are curved substantially half-round and interlock with eachother as plainly shown in Figs. 1, 2 and 4 when the awning is in openposition, and slide apart as shown in Fig. 5 when the awning is inpartly folded position. When the awning is completely folded thesupporting expanding arms are in contact with each other except theupper ends of the two lower arms which remain apart as they are bothattached to the lower slat as plainly shown in Fig. 5. The awning isprovided with a rope or chain 26 at each end that pass over pulleys 21with the outer ends attached to the lower arms or brackets at 28. Theropes or chains are adapted for manual operation for pulling the awningto its folded position adjacent the window frame 2 9. A cornice 31] isattached in fixed position adjacentthe top edge. of the awning. It isprovided with a curved edge 3! for interlocking with the upper edge ofthe top slat- From the foregoing it will appear that an awning madeaccording to the present invention will be easy to install over theupper part of a window by attaching with screws to the outer frame ofthe window. In open condition for use it will cut out sun rays, be waterproof in its interlocking joints, and permit plenty of ventilation whichis an important feature. In its folded condition, it will be positionedadjacent the window frame and cause very little obstruction to sun rays.

The awning may be made of any material suitable for the purpose, but Iprefer to use aluminum for all parts except steel where necessary. Alsothe awning may be made in different sizes and capacities, depending onWhere to be used.

While I have shown and described the preferred embodiment of myinvention, I do not wish to limit same to the exact and precise detailsof structure, but reserve the right to make all modifications andchanges so long as they remain within the scope of the invention and thefollowing claims.

Having described my invention I claim:

1. A metal folding awning of the character described comprising, aplurality of slats, each slat being elongated in form and being straightand curved in cross section, the long edges of each slat defining anapproximate half-circle, one of said curved edges being turned from oneface of the slat, the other edge being turned from the opposite face ofthe slat, the normally lower one of said slats having two bracketsattached at each end thereof, the other slats having one bracketattached at each end of each slat.

2. A metal awning of the class described according to claim 1, wherein,a supporting assembly of expandable arms are attached to each end of thesaid slat brackets, said arms holding the curved edges of successiveslots interlocked with each other when the assembled awning is in opencondition and holding the slats overlapping each other when the awningis in folded condition; a cornice positioned along the top edge of theawning, the outer edge of the cornice defining an approximatehalf-circle and being interlocked with the top edge of the upper slatwhen the awning is in open position and having its curved edge spacedapart from said edge of the upper slat when the awning is in foldedposition; said awning being operable by strand and pulley means, saidmeans including strands attached to the respective lateral ends of theassembly, one end of each strand being attached to the adjacent lowermember of the expansible arms, each strand passing through theassociated pulley and the free ends of the strands being manuallyoperable to open and fold the awning.

3. A metal foldable awning of the class described comprising, aplurality of slats forming a nested assembly, each of said slats beingelongated in form and being flat with its long edges curved to anapproximately half -circle, one of said curved edges being turned fromthe plane of one face of the flat portion and the other edge beingturned from the opposite face thereof, the normally lower slat of theawning having two brackets attached at each end thereof, the other slatshaving one bracket attached at each end of each slat; a supportingassembly of expandable arms mounted in each end of the awning andpivoted together, the upper ends of the arms pivotally attached to thebrackets on the respective slats, said arms holding said slats withtheir curved edges successively interlocked when the assembled awning isin open position and holding the slats overlapping each other when theawning is in folded position; a cornice positioned along the upper edgeof the 4 upper slat, the outer edge of the cornice defining anapproximate half-circle and this edge being interlocked with the topcurved edge of the top slat when the awning is in open condition andspaced apart from the curved edge of the top slat when the awning is inits folded condition; rope and pulley means mounted in each lateral endof the awning, said means consisting of a rope attached in each end ofthe assembly with one end of the rope being attached to the lower memberof the expandable arms and the rope passed through a pulley, the awningbeing manually operable by the free ends of said ropes.
